It was Garrett’s customers — yes, Chicagoans ourselves — who invented the immensely popular sweet-savory Garrett Mix. For years, patrons frequently requested extra paper bags to mix what were then Garrett’s two signature flavors, the tangy cheddar-coated CheeseCorn and the crunchy CaramelCrisp. So, in 1977, the shop started selling the flavors premixed. That mix is available in bags at the shops or online in dangerously large sharing tins (the “celebration” option serves up to 50). $4.75/small bag; $7.85/large bag; multiple locations
